Heya!!!
Alfa + Beta = -q/p
And
Alfa × Beta = 8/p
1/ ( pAlfa + q ) + 1 / ( pbeta + q ) = ?
______________________________
=>{ p ( Alfa + Beta ) + 2q }
__________________
pq( Alfa + Beta )+ p² Alfa × Beta +q²
=>
q ( p - q ) / 4p²
Alfa + Beta = -q/p
And
Alfa × Beta = 8/p
1/ ( pAlfa + q ) + 1 / ( pbeta + q ) = ?
______________________________
=>{ p ( Alfa + Beta ) + 2q }
